Many reports in the past hour or two suggesting that Obama is about to cave on the fiscal cliff — water down his tax demands in return for some minor Republican concessions — concessions that won’t involve taking the debt ceiling off the table.

This is the anger in a nutshell. Not fighting hard enough on taxes, and opening himself up to being rolled on the debt ceiling again in a couple of months.

For those not familiar with poker strategy, a "tight-weak" is a player who doesn't contest many pots, but then when they do get into a hand, they don't play aggressively. It's okay not to pick many fights, but when you do, you should try to take down big pots with strong hands. The frustration is that Obama doesn't fight the big ones hard.
